Abu Hurairah (Radiyallaahu `anhu) reported Allah’s Messenger (Sallallaahu `alayhi wa sallam) said:
“The servant speaks words that he does not understand its repercussions but he sinks down in Hell-Fire farther than the distance between the east and the west.”

The prophet (s) is talking about two important issues. The evil of talking without thinking about the consequences of your words and the vastness of hell.
May God saves us all from the fire.
